Hee. We've just started watching some classic Who here, beginning with Four, and since so far we've seen a blatantly toy tank shot in close-up to look like a full-size one in Robot, and a space station that's clearly made of about three bits of plastic junk painted white in Ark In Space, I doubt that dodgy science is going to be top of my fail list.

I think I've become inured to all that. And the technobabble. But this really stuck out like a sore thumb - on a level with confusing the galaxy with the solar system, which also happens from time to time.
